That is the opinion of a chap called Professor Gautam Kalghatgi, (The spelling is correct btw). I listened to him being interviewed earlier, he said electric cars are unsustainable and will be our next environmental disaster. He went on; we are currently 80% reliant on fossil fuels, to reach net-zero we would have to close down much of our industry and build 90 new nuclear power stations which would be unlikely by the end of the century let alone 2035. He said, mining lithium is destroying once pristine environments and that lithium mining is dirty and toxic, and we haven't even scratched the surface on the amount we will need to reach net-zero. He said small petrol engine cars can be environmentally friendly, unfortunately a lot of R&D has been scrapped due to net-zero. I don't have a link to prof Gautam, I listened to him on Talk TV however I did find this on lithium mining: The spiralling environmental cost of our lithium battery addiction - www.wired.co.uk/article/lithium-batteries-environment-impactAlso on the same programme, a chap phoned in who worked in the offshore wind industry. He said wind power is an absolute con (His words) He said the blades are supposed to have a 25 year life span, yet he is replacing blades after as little as five years due to the leading edge becoming pitted and corroded from grains of sand, they cant be repaired and are sent to landfill. He said the (electricity) cables also have to be replaced at regular intervals and the maintenance costs are sky high. Allow me to remind you what goes into one wind turbine: 335 tons of steel 4.7 tons of copper 1,200 tons of concrete (cement and aggregates) [~600 yards] 3 tons of aluminium 2 tons of rare earth elements aluminium zinc molybdenum And wind power is sold to us as the environmentally friendly answer? We must be right mugs to believe this nonsense. |

Seems like the wrong attitude to me
Perhaps current technologies aren't the answer, maybe its not as black and white as that and they are part of it but not all of it.
Often setting a goal and striving for it, however improbable that goal might seem to be to some, is how great things are accomplished because that goal will serve to organize and measure the best of our energies and skills, because that challenge is one that we are willing to accept, one we are unwilling to postpone, and one we intend to win

Anyone who 'seriously' thinks net-zero is achievable by 2035, or 2030 according to Starmer lol, is away with the environmental fairies. It's just not going to happen.

He may be right but, given his Aramco background, he doesn't really fit the role of disinterested witness.

We wouldn't even be looking at electric cars if we didn't have places like China where regulations are so lax that polluting the country for the chemicals to make batteries is seen as acceptable..

Why? He is an academic not a politician and he is very highly regarded which is why he has been invited to speak at universities all over the world. He says small petrol engine cars are the future, not electric cars. And I'll tell you something else, more and more people are slowly coming around to the fact that electric lithium-ion powered cars are probably not the future. |

Cadent is replacing the lining of gas pipes through England ( maybe UK) and has to complete by 2030. Old pipes can be made of steel . These need to be replaced steel because hydrogen ( which will be added to natural gas) destroys steel. Air source pumps are useless and electric combi boilers eat electricity. The infrastructure for charging electric cars is pathetic too. |

Because he worked for oil companies for ~40 years.

I recently listened to a chap who had at considerable expense had a heat pump installed. It was great in the summer, but didn't heat the house enough to keep him and his family warm in the winter, so to compensate for the useless heat pump he had a wood burner installed. Go figure. www.telegraph.co.uk/money/consumer-affairs/expensive-wasteful-heat-pumps-not-solution-britains-energy-crisis/ |

Yes I know, actually I thought it was 30 years, not that it matters. And anyway, that doesn't have any bearing on my previous post. |

I tend to think his opinion would carry more weight if he were not an oil man (retd.). I think that's more than a little unfair. As I said, he is not an environmentalist or a politician, he is a well respected academic. Dr.Gautam Kalghatgi, FREng, FSAE, FIMechE, CEng joined Saudi Aramco in October 2010 after 31 years with Shell Research in U.K. He has over a hundred external publications on combustion, fuels and engine research and is the author of a book, "Fuel/Engine Interactions". He is a Fellow of the Royal Academy of Engineering, SAE and I.Mech.E. He is a Visiting Professor at Imperial College, London and has been adjunct/part-time/visiting Professor at KTH, Stockholm/ Technical University, Eindhoven/ Sheffield University.

Quote from the above link:
So in summary, there is no empirical evidence that there is an “existential threat”. The world is a far better place in almost all countries not affected by war, compared to the past. Of course, there will be some consequences of increasing temperature because of increasing greenhouse gases but as economies grow, they will be better able to cope with these changes and for growth, you need affordable energy.
The targets to decarbonize any economy by 2025 or 2030 are unachievable, in my opinion. It is dishonest or naïve to believe that it will be possible to achieve such targets in democratic societies. If such rapid changes are forced, there will be terrible economic and environmental consequences.
Gautam Kalghatgi FREng FSAE FIMechE FCI FISEES.
That's not political. It's common sense.
